Reference is made to FIG. 2B, which is a diagram of an N-th stage shift register circuit 200′ according to an embodiment of the disclosure. The N-th stage shift register circuit 200 can be applied to the N-th stage shift register circuit 110(n) shown in FIG. 1. The 200′ also includes the 210 and the 240, but a first output unit 220′ and a second output unit 230′ do not include the first capacitor C1 and the second capacitor C2.

From the viewpoint of circuit analysis, the effective capacitance of the circuit looking from the first operation node Q includes an input capacitance Cgs3 of the third transistor M3 and an input capacitance Cgs4 of the fourth transistor M4. The effective capacitance is sufficient for maintaining proper operation of the first operation node Q. Hence, in this embodiment, the circuit area can be reduced substantially by reducing capacitors in output units.

Besides, a driving method 300 is proposed in this disclosure. The driving method 300 is configured to drive the shift register circuits 110(1)-110(n) of the driving circuit 100 in, but not limited to, the aforementioned embodiments. Reference is made to FIG. 3A and FIG. 3B. FIG. 3A is a diagram of the driving method 300 according to one embodiment of the disclosure, and FIG. 3B is a timing diagram of the signal of the N-th stage shift register circuit 200 shown in FIG. 2A.

Operation S310 of the driving method 300 is performed. In a first time interval T1, the enabling control unit 210 configures the first operation node Q to a first enabling level according to the enabling signal STV. As shown in FIG. 3B, in the first time interval T1, the enabling signal STV is at logic-high level, and the first transistor M1 is hence turned on and raise the voltage level of the first operation node Q to the first enabling level. The first enabling level is the voltage level of the first operation voltage FW, and as mentioned above, the first operation voltage FW can be at logic-high level. It is noted that, although the first operation node Q is at logic-high level during the first time interval T1, the first clock signal CK1 and the second clock signal CK2 is not enabled. Thus, the third transistor M3 and the fourth transistor M4 does not generate the first driving signal G(2 n−1) and the second driving signal G(2 n).

Operation S320 of the driving method 300 is performed. In a second time interval T2 after the first time interval T1, the first output unit 220 generates the first driving signal G(2 n−1) at the output terminal of the first output unit 220 and configures the first operation node Q to a second enabling level by enabling the first clock signal CK1. As shown in FIG. 3B, in the second time interval T2 after the first time interval T1, the first clock signal CK1 is at logic-high level, thus the first terminal of the third transistor M3 generates a logic-high first driving signal G(2 n−1). Meanwhile, due to the coupling effect of capacitors, the first capacitor C1, the second capacitor C2 and the Input capacitance Cgs3 of the third transistor M3 and the Input capacitance Cgs4 of the fourth transistor M4 further raise the voltage level of the first operation node Q from logic-high level to the second enabling level, which is about twice as high as the logic-high level. Note that, even if the driving method 300 is applied to the N-th stage shift register circuit 200′ in FIG. 2B, the Input capacitance Cgs3 of the third transistor M3 and the Input capacitance Cgs4 of the fourth transistor M4 is still enough to raise the voltage level of the first operation node Q from logic-high level to the second enabling level.

Operation S330 of the driving method 300 is performed. In a third time interval T3 after the second time interval T2, the second output unit 230 generates the second driving signal G(2 n) at the output terminal of the second output unit 230 and configures the first operation node Q to a third enabling level by enabling the second clock signal CK2. As shown in FIG. 3B, in the third time interval T3 after the second time interval T2, the second clock signal CK2 is at logic-high level, thus the first terminal of the fourth transistor M4 generates a logic-high first driving signal G(2 n). Namely, due to the coupling effect of capacitors, the first capacitor C1, the second capacitor C2 and the input capacitance Cgs3 of the third transistor M3 and the input capacitance Cgs4 of the fourth transistor M4 further raise the voltage level of the first operation node Q from second enabling level to the third enabling level, which is about three times as high as the logic-high level.

Operation S340 of the driving method 300 is performed. In a fourth time interval T4 after the third time interval T3, the first operation node Q is configured to the second enabling level by disabling the first clock signal CK1. As shown in FIG. 3B, in the fourth time interval T4 after the third time interval T3, the first clock signal CK1 is switched from logic-high level to logic-low level thus the third transistor M3 stops generating the first driving signal G(2 n−1). Besides, because the first clock signal CK1 and the third clock signal CK3 are complementary, when the first clock signal CK1 is switched from logic-high level to logic-low level, the third clock signal CK3 will be switched from logic-low level to logic-high level, and the voltage level of the output terminal of the first output unit 220 will maintain at the reference voltage level VSS via the sixth transistor M6. On the other hand, the second clock signal CK2 maintains at logic-high level at this moment, thus through the coupling effect of capacitors, the voltage level of the first operation node Q is pulled low from the third enabling level to the second enabling level, which is twice as high as the logic-high level.

Operation S350 of the driving method 300 is performed. After the fourth time interval T4, the disabling control unit 240 is driven by the first clock signal CK1 to maintain the voltage level of first operation node Q at the reference voltage level VSS. As shown in FIG. 3B, after the fourth time interval T4, the second clock signal CK2 is switched from logic-high level to logic-low level thus the fourth transistor M4 stops generating the second driving signal G(2 n). In addition, since the second clock signal CK2 and the fourth clock signal CK4 are complementary, when the second clock signal CK2 is switched from logic-high level to logic-low level, the fourth clock signal CK4 will be switched from logic-low level to logic-high level, and the voltage level of the output terminal of the second output unit 230 will maintain at the reference voltage level VSS via the eighth transistor M8. On the other hand, since the shift register in this stage has successfully output the first driving signal G(2 n−1) and the second driving signal G(2 n), the voltage level of the first operation node Q is not necessary to maintain at logic-high level. Thus, the voltage level of the first operation node Q is pulled low to the reference voltage level VSS via the reset signal RST, and the voltage level of the first operation node Q maintains at the reference voltage level VSS by the first clock signal CK1.

As additional remarks, in some embodiments, the driving method 300 still includes step S360 (not shown in figures): In the fourth time interval T4, the shift register in the next step generates corresponding first driving signal G(2 n+1). As previously mentioned, in some embodiments, the second driving signal G(2)-G(2 n) in each stage of the shift register circuits 110(1)-110(n) is the enabling signal STV in the next stage. Therefore, if the second driving signal G(2 n) enabled in the third time interval T3 is regarded as the enabling signal STV in the next stage, e.g., (N+1)th stage (not shown in figures), then in the third time interval T3, the corresponding first driving signal G(2 n−1) in the next stage, i.e., (N+1)th stage, will be generated.

To conclude, outputting at least two driving signals are generated in a single stage by sharing the enabling control unit and disabling control unit in the same stage of the shift register circuits. Moreover, in some embodiments, the circuit area can be substantially reduced through decreasing the number of capacitors in output units.
